“…For the mixed forest of northwest Patagonia, (particularly for the southwest of Rio Negro and northwest of Chubut), the presence of obsidians from outcrops in the area of the Somuncura Plateau are recorded, though they are absent in our research area. The MS1 source of the Somuncurá Plateau has been recorded since the Early Holocene (8,230 years BP) in the Población Anticura (Bellelli et al 2018). For the Late Holocene obsidians have been recorded from Sacanana 1 (S1), Portada Covunco and Laguna La Larga (Bellelli et al 2018;Castro Esnal et al 2011;Fernández & Vítores 2015;Podestá et al 2007).…”

“…In Neuquén its use is recorded in archaeological sites close to the sources since 3500 years BP, until historical times. It was transported hundreds of kilometres to the east and south (Bellelli et al 2018;Favier Dubois et al 2009;Stern et al 2012). Obsidian from the Neuquén source Portada Covunco is underrepresented in northern Neuquén .…”

“…Obsidian from the Neuquén source Portada Covunco is underrepresented in northern Neuquén . However, it increases and is distributed relatively systematically to the south, reaching to the province of Chubut Bellelli et al 2018;Pérez et al 2015;Stern et al 2012).…”

“…For the Late Holocene obsidians have been recorded from Sacanana 1 (S1), Portada Covunco and Laguna La Larga (Bellelli et al 2018;Castro Esnal et al 2011;Fernández & Vítores 2015;Podestá et al 2007). The representation of this rock is very low and the artefacts are very small, possibly linked to a need to ensure the availability of raw material of excellent quality in an environment in which it is not present (Bellelli et al 2018).…”

“…Neither obsidians from the Somuncurá Plateau (MS1), Río Negro and Chubut provinces, nor from the sources located at the southern edge of the Somuncura Plateau: Telsen -Sierra Chata I and II in Sierra Negra and Cerro Guacho, located in the paleocauce of the Sacanana stream, have been recorded in La Pampa. These sources, located in the Patagonian plateau, have a wide dispersal, varying between 100 to 800 km (Bellelli et al 2018;Gómez Otero & Stern 2005;Stern et al 2000). However, we do not expect to find obsidians from El Peceño because its distribution rarely exceeds 70 km (Giesso et al 2011).…”

The goal of this study is to report the progress regarding the procurement and circulation of obsidian by hunter-gatherer populations during the Late Holocene in the province of La Pampa, Argentina. A total of 25 samples were analyzed in two stages; in the first stage neutron activation analysis (INAA) was used, while X-ray fluorescence (XRF) was employed in the second stage. This work adds nine archaeological samples from new sites and one from the Lihué Calel obsidian source. The results allow us to take into account the sourcing of the obsidian which was found in archeological sites of four areas of study located in the south and east of the province. Both, the results generated in this new stage, and those previously obtained are integrated and discussed in relation to the information produced by other researchers from the region, which are consistent with the existing ones for La Pampa. They indicate that the obsidian recovered was procured from sources located in the Argentinian and Chilean Andes, as well as the pre-cordillera in the provinces of Neuquén and Mendoza. New data expands the spatial perspective of our interpretations to four new research areas: Curacó basin, Lihué Calel hills, Valles Transversales (Transversal Valleys) and Bajos sin Salida (Endorheic low areas).
